SPECIFICATION forming part of Letters Patent No. 348,076, dated August24, 1886.

Application filed March 6, 1885.

To all whom it may concern.-

Be it known that I, ALBIN WARTH, a citizen of the United States,residing at Stapleton, in the county of Richmond and State of New York,have invented new and useful Improvements in Steam Pumping-Engines, ofwhich the following is a specification.

This invention relates to pumping apparatus; and the object of theinvention is to provide a pump which will operate easily, and the partsof which can be readily put together and taken apart. The pump-valve canbe operated by a piston, and suitable cushions can be provided toprevent slamming or jamming of said piston. The pump-valve chamber maybe provided with small openings to prevent the operation of the valvefrom being disturbed.

This invention is illustrated in the accompanying drawings, in whichFigure 1 represents a plan or top view. Fig. 2 is a longitudinalvertical section in the plane at m, Fig. 1. Fig; 3 is a similar sectionin the planey 3 Fig. 1. Fig. 4 is a transverse vertical section in the'plane 2 2, Fig. 3. Fig. 5 is a similar section in the plane 00' m, Fig.3.

Similar letters indicate corresponding parts.

In the drawings, the letter A'designates the main cylinder. 13 is thepumpcylinder. O is the valve-chamber. D is the pump-valve.

E is a secondary cylinder, by means of which motion can be imparted tothe pumpvalve D.

E is the piston of the main cylinder A.

The piston E can communicate motion to the pump piston or plunger G bymeans of a piston-rod, F.

On the piston-rod F is firmly mounted or secured a collar or shoulder,a. When the piston-rod F is in motion, the collar or shoulder a actsfirst upon one arm and then upon another arm of a lever, b. Thedouble-armed lever b oscillates about the fulcrum or pivot c, andcommunicates motion to an arm or lever, d. The shaft or pivot 0 can beprovided with ahub, b, Fig. 2, to which hub the lever d can be secured.The lever d is connected by alink, c, with a rod or arm, f. The rod orarmf imparts motion to the valve H of the secondary cylinder E, Figs. 1and 3. The rock-shaft or pivot c has its bearing in the main frame I.The piston J of the secondary cylinder E connects by a rod, K, with apump- Serial No. 157,949. (No model.)

valve, D. The rod K is connected by a linli, h, with a lever, i. Thelink h may connect with the rod K by means of a collar, 9, which collarcan be screwed or firmly secured to the rod K, Fig. 3. The lever t'imparts motion to rockshaft j. The rock-shaftj has its hearings in astandard, It. The standard It can be secured to the main frame I. Therook-shaft 7' imparts motion to a lever, 2' which connects by a link, Z,with a rod or arm, 122*. The rod m* imparts motion to the valve L of themain cylinder.

From this description it will be understood that the valve H of thesecondary cylinder E is actuated or changed by the action of the pistonE of the main cylinder A, and the valve Lof the main cylinderA isactuated or changed by the action of the piston J of the secondarycylinder E. The valve-chest L of the main cylinder is provided with asupply-pipe, M, and with an exhaust, N, Fig. 1, and said valvechest Lcommunicates with the main cylinder A by ports at m", and with theexhaustN by the port a, Fig. 2. The valve-chest 11 of the secondarycylinder is provided with a supply-pipe, P, and with an exhaust, Q, Fig.1, and it communicates with said secondary cylinder by ports 19 p", andwith the exhaust Q by the exhaust-port q, Fig. 3. Ad-

. ditional ports r 1" lead from the valve-chest H to the annular grooves1 H, which surround the piston-rod K, and in this piston-rod K, on eachside of the piston J, areaseries of cavities,

s s, the object of which will be presently morefully explained. Thepump-valve D is composed of two pistons, d d*, which work in a lining,C", which lining is made of metal or other suitable material, and whichlining is firmly secured in the valve-cylinder or valvechamber 0, andwhich is provided with three sets of openings, t t t which communicatewith annular grooves a a 10* in the inner surface of the valve-cylinderO. The groove u connects, through a channel, '0, Figs. 2 and 4, with theouter end of the pump-cylinder B, the groove u connects, through achannel,o, Fig. 2, with the inner endbf the pump-cylinder B, and thegroove a connects, through port o"*, Figs. 3 and 5, with thesuction-pipe S. The ends of valve-cylinder 0 connect, through ports w20,with the discharge-pipe T, Figs. 3 and 5, and the ports w w alsoconnect with the air-chamber U, Fig. 3. In the position shown in thedrawings, the piston E has ICC) just completed its outward stroke, andthe pump-piston O has forced the water or fluid in front of it throughtheport v groove u", holes t", and port w to the discharge-pipe T, whilewater has been sucked in from the suctionpipe S, port v*, annular grooveu*, holes t*, holes t, annular groove u, and port 1;, into thepump-cylinder B. In order to drive the piston Einward, the slide-valve Lmust be changed, and this change is effected by the piston J of thesecondary cylinder E. By referring to Fig. 3 it will be seen that steamor motive fluid passes through port r, groove r*, and recesses 8 intothe inner end of the cylinder E, and consequently the piston J is drivenout:

ward, and by the time the recesses s have passed the groove 1* thepiston d" of the pumpvalve D has passed over the holes t, so that t" t*get between the two pistons d d of the fluid-valve, and at the same timethe slidevalve L of the main cylinder has become changed by the actionof the collar g, link h,

levers i i", link Z, and rod m, the main piston E begins its inwardstroke, and the water contained in the pump-cylinder is driven throughport 1), annular groove u, holes t, and port 10 to the discharge-pipe T.During the inward stroke of the piston E the slide-valve H of thesecondary cylinder is changed, steam or motive fluid is admitted to theouter end of this cylinder, and the different parts are brought back tothe position shown in the drawings.

The object of the supplementary ports 1' r in the secondary cylinder,and of the recesses 8 8 in the piston-rod K, is twofold: First, to admitsteam or motive fluid to the cylinder E before the slide-valve H hasbeen changed, and, second, to provide a steam or fluid cushion in frontof the piston J, to prevent the same from slamming.

\Vhen steam is employed to operate the pump, the'cushion which isprovided for the piston J is formed by live steam,whicl1, being underhigh tension, forms a very elastic and effective cushion.

In addition to the provision made for cushioning the piston J by steamor fluid, I have also applied cushions V, of rubber or yieldingmaterial,which limit the movement of the collar g, and consequently ofthe piston rod K.

From the foregoing description, and from the inspection of the drawings,(particularly Fig. 3,) it will be seen that the pump-valve D isbalanced, or nearly so, at all times, the outer heads of the pistons d"d"* being always exposed to the pressure of the column of water or fluidcontained in the discharge-pi pe, while the inner heads of said pistonsd (1 are always exposed to the suction, and consequently it takescomparatively little power to move the pumpvalve, andI am enabled to runmy pump with very great speed to force water or other liquid to aconsiderable height with comparatively little strain on the workingparts.

My pump can be used for pumping liquids or gases, and in certain casesthe motion can be imparted to the pump-piston by hand or other power, soas to dispense with the steamcylinder.

In constructing my pump I prefer to sup port the main cylinder A and thepump-cylinder B,with their adjacent parts, u pon afiame, I, and tosupport or partly support the secondary cylinder E and the valvechamberO, with their adjacent parts, upon a secondary frame, I. Parts of thepump which need examination or repairing can thus be readily detachedwithout disturbing the remainder of the mechanism. It is also to benoticed that the holes tt t* in the valve-chamber are preferably made sosmall as to prevent any material entering the valve-chamber which wouldbe likely to interfere with the operation of the valve D, and thepacking of the pump-valve D, which often is soft or yielding, is keptfrom catching or tearing, as the lining 0" allows the valve D to move orslide easily, and the holes in the lining O are so small that thepacking of the valve D cannot strike or tear against the edges of theholes t t" t*. The valvechamber 0 can be connected to the pump-cylinderB by bolts or screws, so that said valvechamber 0 can be readilyattached to or detached from the apparatus.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a main cylinder, A, and its valve, of apump'cylinder, B, pumpvalve D, secondary cylinder E, a rod connectingthe piston of the secondary cylinder with the pump-valve, mechanism foractuating the valve of the main cylinder by the piston of the secondarycylinder E, mechanism for actuating the valve of the secondary cylinderby the piston of the main cylinder, supplementary ports leading into thesecondary cylinder E, and recesses in the piston-rod of said secondarycylinder.

2. The combination of the main cylinder A, pump cylinder B, secondarycylinder E, valvecase 0, pistons E J, rods F K, cylinder'valves H L,levers b d, link e, and rod f, for actuating the valve of the secondarycylinder from the piston-rod of the main cylinder, and the link h, levert', rock-shaft j, and means for connecting said rock-shaft with thevalve of the main cylinder, whereby said valve is actuated'from thepiston of the secondary cylinder, substantially as described.

3. The combination, with the pump-valve D, piston J, and pistonrod K,having collar 9, of the cushionplates V, link h, lever i, rockshaft j,lever 1", link Z, and rod or arm m*, for actuating the valve of the maincylinder, sub stantially as described.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witncsses.
